To all'whomvit-mag concern:

Be it known that we, ANTOINE GHIs ALBERTI, of2 Quai de la Rape, Paris, France, manufacturer, and AUGUSTE BLAIsE BAnom'of 155 Boulevard de Magenta, Paris, France, engineer, have invented Slicing- Ma-chines, of which the following is aclear, full, and exact description.

This invention has'for its object a machine more particularly adapted for cutting ordinary meat, sausage, ham, etc., into slices of determined thickness which may be varied at will, but the said machine may also loe used for cutting into slices eatables and other like'produc p v The'improved slicing machine is essen& tially characterized by a frame carrying the circular knife, the to-and-fro motion of which produces the rotation of the knifeand determines the forward movement of'a V carriage carrying the product to be cut in slices.

The knife carrying frame acts, for that purpose, on the actuating members of the carriage carrying the product to be cut, in such a manner that upon each return movement of this frame, the car iage is moved forward according to av distance correspond ing to the desired thickness .of the slice, whichis then out during the following forward movement of the said frame.

The accompanying drawings illustrate, by way of example only, a slicing machine made according to this invention.

Figure 1 is a front view of the upper portion of a machine embodying the inventicn, a portion of the frame being in section to show more clearly the feed mechanism and the partsintimately associated there with. i L Fig. 2 is a top plan view of the machine.

As shown inthedrawings, the improved 7 machine comprises a base or frame a cont posed oftwo Vertical cheeks and. supporting a second transverse frame I; in which can slide the carrier 0 supporting the circular knife d.

This carrier 0 supports, moreover, a

of the toothed wheel 6 and that the I Specification of Letters Patent. Patented F b. 22 1921 A pplication i'iled December 17, 1919. Serial No. 345,648.

toothed wheel 6 loose on axis 6 and gearlng, on the one hand, with a rack f arranged at the upper part of the transverse frame I) a and, on the other hand, with a pinion g lntegral wlth'the circular knifedf It results from this arrangement that,

when the carrier cismoved longitudinally consequently, the circular knifed the axis d of which turns'freelyin the carrier 0 As the diameter of thew'heel cjismuch greater than that ,of thepinion 9, it results therefrom that this pinion and the knife d,

with which it is integral, are driven with speed of rotation much greater than are thus easily cut into slices. I

The shaft cl of the knife d carried as above mentioned by the carrier-'0 serves, in

the example illustrated, as rocking axis-for f;

aconnecting rod or link it the forked end of which lshlnged toa lev'erI carrying at its at the opposite end, on'an axis a yoke 1 secured to the frame a. 1

products upper part a driv ng handle 2' andplvoting', 5 j carried in It will thereforef'be'seen' thatbyimpart- I ingto the lever .2 a backward movement and then a forward movement, the/carrier c and the knife '0? supported by the latter are moved either foinvard or backward and that at the same time this knife receives a rotary movement sufficient for allowing to easily out in slices the mostresistant edible prodnot orthe likeplaced on thelcarriage' 7c.

The mechanism for moving forward this I carriage as well as the device allowing to regilate the thickness of the slice to be out are 'inclosedbetween two cross-pieces Z arrangedbetween the checks of the fr'ame a.

This carriage 7c1is'somounted as to be able to slide between the cheeks of the frame a on a plate a of less width than the inter:

tuated in the following manner:

The carriage his connected, at each of cable-0 one of the endsof which is attached the tension of the said cable.

This cable 0, in'closed'in a suitable-casing, passes on a roller 9, then on theiguide rollers to a stretching device p allowing to adjust val separating the said cheeks and 1t1sac- 1' and winds on a drum 8 which carries, on one of its faces, a ratchet wheel t. v 1

The intermittent actuation of the ratchet Wheel 23 and, consequently, the forward movement, also intermittent, of the carriage 76 supporting the product to be cut, are obtained in the following manner: I

A rod a is mounted in the frame I) so as to be able to move longitudinally in the latter; this rod carries, for that purpose, at one of its ends, a heel piece u which is guided in a slide 6 of the frame I) and held against the rear face of the knife carrier 0 by spring uflas shown in Fig. 4:. I d

On the other hand, this rod it carries, at the end opposite to the heel piece a aipawl u fwhich is held in contact with a ratchet wheel 1, integral with the drum ,8 of the .cable o.' i i It results from this arrangement that, each time the carrier 0 is moved backward again,

. after cutting a slice of the product, its rear face comes in contact with the heel piece or abutment u of the rod to which is then moved backward as well as the pawl a carried by the latter.

This pawl then actuates the drum 8,

through the medium of the ratchet wheel t and thus causes the carriage k to move forward according to a length the value of which is determined by the stroke allowed tothe abutment a and'which may be adjusted at will as will be explained hereafter.

A The actuating pawl a rocks and is'carried by the end of a tube'% secured in another 7 tube a in which can slide the rodu.

, Thereturningspring a normally tends to move forward'the tube '11 and pawl a this spring a is attached, on the one hand,

to a fixed point Z of the cross-piece Z and, on the other hand, to a study/f secured to the tube 'wand capable of moving in a horizonf tal slot l of the said cross-piece (Fig. 4c).

i The rodu carrying the pro ection a and arranged in the tube a is surrounded by a shock-absorbing spring 14 taking a bearing,

at one of its ends, on the bottom of the tube a and, at the opposite end, against a screw or abutment u integral with the rod u and projecting in slots a made in the tube 'ui.

" -It results from this arrangement that,

when the tubeu? is stopped in its backward movement by the engagement of the stud u with an adjustable stop rod 15, the pawl a actuating the carriage 7c is also held stationary and that the remainder of the return movement of the knife-carrier 0 produces no longer the actuation of the rod wand the compression of the shock-absorbing spring 1 1 in the tube a.

'When the carrier 0 is again moved forward for cutting a new slice, the projection u is released, so that the whole of the rod a, tube a and pawl 20 moves forward under the action of the returning spring 20 The movement of the tube is limited in this direction by the projection u which strikes against the bottom of a slot 6 formed in the lower part of the fixed frame I).

The rocking pawl a is connected to the retaining pawl 2 by a coil spring 16 holding the said pawl z in engagement with'the ratchet wheel t and the rocking pawl u in suitable position for moving the said ratchet wheel. i i l r The retaining pawl a, which rocks freely on an axis 2 carried by the cross-piece i is also held in contact, by the spring 16, with a cam 17 fast on an axis18 and provided with a small operating lever 19 which can take the positions I and 11 (Fig. 1), so as to release the ratchet wheel t from the retaining pawl 2, when the'meat-carrying carriage is to be brought backward. V i

The crosspiece Z is perforated, in addition to the opening'l for guiding the stud at, with an orifice Z allowing the passage of a cable 0 windlng on the drum 8, passing on the rollers 1" and the roller 9 and attached to tension shackles p. i

The adjustment of the thickness of the slices is obtained by means of the stop rod 15 sliding through the cheeks a and in a suitable slide 6 of the transverse frame 6, as well as in an opening 00?, of one of the cheeks a (Fig. i F

This rod 15, the end of which is arranged opposite to the stud u, terminates at its other end by a projection or heel 17 which allows of moving it by hand forward and backward according to the desired thickness of the slice to be cut. This rod is provided, for

that purpose, with a number of notches 18 which indicate, according to the position they occupy near the slide 19, the thickness chosen corresponding to a greater or less spacing apart of the end of the rod 15 and the stud u? integral with the tube 715 7 It will be seen, by referring to Fig. hthat the adjustment of the interval separating the rod 15 and the stud u allows of varying the backward stroke of the tube a and pawl u and, consequently, the value of the driving movement of the ratchet wheel t and drum scontrolling the carriage k,- a greater or less forward movement of, the product to be out opposite the knife is thus produced, the compression of the spring 14 deadening the shock of the knife-carrier c and thus al- A carriage 21 is mounted, so as tobe capable of sliding between the checks of the frame a, on a plate a of less width than the interval separating ,the said cheeks. It is connected, on each of its-edges, by bolts 22 passing freely through the slots 0 B between the cheeks a and the plate a to a counter-plate 23 to the lower part ofwhich is attached'the driving cable 0, the ends of which are secured to tension shackles 10 allowing to adjust the tension of the said cable. a s

It will therefore be understood that, according to the direction of the movement imparted to the cable, the carriage 21 will be moved forward or backward on the plate a a r i This carriage supports, onits two, vertical sides, two slides 24 adapted to receive'the vertical posts 25 of a second: carriage k, called meat carrying carriage.

A second carriage which is rendered integral with the firstcarriage simply by the engagement of its posts 25 in the vertical slides 24 of the first carriage, is therefore readily removable, so that itis possible to replace it at will by another similar carriage supporting another product to be cut.

This product, meat or the like, is'held in:

place on the' meat carrying carriage by means of a plate26, ofsutficient weight,

sliding with a slight friction on the posts 25' and provided, on its lower face, with points 27 entering in the meat, thesaid carriage is being provided for the same purpose, on its upper face, with retaining points 28 also entering into the meat.

The apparatus is completed by a covering plate 29, arranged on the checks (4 and in front of the slide 6 the cheeks being, on the other hand, suitably spaced apart bythe cross-pieces 30'and 31, on the'last of which I is mounted the roller 9 of the cable 0.

The above'describedmachine is more particularly intended to cut in slices edible products such as meat, bread, etc., but it is obvious that it may be used such as it is described, or with slight detail modifications, for cutting in slices any product whatever.

The constructional arrangements are given onlyby way of example; the forms,

materials, dimensions, as well as the accessory devices may be varied without departing thereby from the nature of the invention.

The knife, for instance, might be replaced, in certain cases, by a circular'saw.

The machine is mounted upon a table or stand 11 as indicated most clearly in Fig. 6. This stand or table which is readily portable must in practice be held stationary. during the operation of the machine. For this purpose it is provided with a pedal 12 having teeth on its inner face and it is mounted in such a manner that when the foot presses ticle carrier, a cutter mounted to reciprocate" across the path of movement of the article carrier, an intermittent feedmechanism for the article carrier including a ratchet mech anism, a movable stop element controlling the pawl ofthe ratchet mechanismand ope rated by the cutter, ,andan. adjustable ele-,
